How difficult is VTU in India?

It's as difficult as it gets. In the second year, more than half of students have a backlog. 

If you are an outsider, you will have to deal with some unpleasant situations as well; you will not receive excellent internal marks, which are 25 points. Expect nothing from your teachers, but this is true throughout India. 

Attendance should be at least 75%. Only a few colleges have severe standards, while others are more lenient. Attendance should not be taken lightly; lack of attendance might result in semester detention, even in the seventh semester. Students fail practical exams here as well, and backlogs are common. You never know what's going to happen.

Regardless of these factors, I recommend that you go for VTU, just remember that you are here to study; you can do other fun things in addition to studying, but you must not neglect study at any cost. 

In VTU, you can’t score well by studying just the night before the examination. You will have to study regularly. If you study hard during the semester, your marks will be good.

To get a good grade, you need to do well in both the internal and practical exams. Then you can only obtain a 60% in the semester; to get a higher grade, you must do well on the final exam. It is difficult to achieve a score of more than 70 out of 100 on an external exam.

Marking method for VTU:

• Internal marks: 25 (assume it's an A)
• Passing grade=50, which equals A+B.

When thinking about passing grades, If you obtain a 0 in internal, you must score 50 in external. Similarly, if your internal score is 15, you must get 35.
